Why use the <div> instead of <ul>?

In this video, Guil uses the <div> element to show how bubbling works. He says for performance reasons it is good to select an element close to the actual target. He uses the <div>, but there is an <ul> element one level closer to the <li>s.

What are some reasons to prefer using the <div> instead of the <ul>?

I think that's because he already set a class for the <div> "listDiv" so that he doesn't have to re-do the process again( select the target, addEventListener...etc.)

"div" elements are usually used for styling purposes in the closer future with help of CSS. Several parts of a document can be wrapped inside a div for example and then give it a certain class; for example "container" and then apply certain styles to that div's class, as I said this is just the best practice it seems and this helps to organize your code in a more cleaner and meaningful way in both your HTML and CSS files. Hope it helps, and if I'm wrong I'd be glad to know :) as I'm also currently learning

I have no idea why your comment was -4 when I saw it. I upvoted it because it seems totally reasonable.

Because it doesn't have anything to do with the answer. Marco is talking about the general meaning of a div element and its uses (correctly), but the question is about something else, very specific to this particular code example. The downvotes come off a bit mean though.
